My Atomos Samurai arrived yesterday, and after trekking to AllTex Electronics to pick up an SSD drive, I finally had a chance to try out the little recorder that I’ve had my eye on since I first saw it behind glass at NAB in 2010. The only SSD that AllTex had in stock that was fast enough, and not insanely expensive, was the 90GB Corsair Force SATA 3. It was not on the Atomos approved list of drives, but I figured with a peak write rate of around 500MB/sec it was plenty fast to record ProRes422 (HQ), which puts data down at around 220MB/sec, give-or-take. It was strange, though, that there was absolutely no information in the Corsair tech specs at the store about the drive’s sustained write rate. I decided to take a gamble on it, and sure enough, it seems to work just fine. After recording a single fifty-five-minute take in ProRes422 (HQ), I didn’t get a single glitch from the drive.

First Impression:
If I had to choose one word to summarize my unboxing experience of the Atomos Samurai, it would be, “impressive.” The unit comes in its own custom hard case, similar to a Pelican, with custom foam inserts and an included shoulder strap. In this case is everything you need to get started using your Samurai, including the recorder, SSD dock, batteries (2), charger, USB cable, USB bus power cable for the dock, and a FW800 cable. An especially-appreciated inclusion were two (2) BNC to Mini BNC adapter cables for your camera’s SDI feed, so that’s one less thing you would have to order separately, as you would with other recorders on the market. In fact, the ONLY two things you have to supply separately of what is in the Samurai’s case is the SDI cable that leads from your camera, and the hard drives to record to.

Immediately after opening the case, it was obvious how nice the build quality is. The Samurai unit and the dock are both very well put-together, and I immediately fell in love with the fact that the dock is bus-powered; you don’t have to plug it into shore power, and this is so incredibly handy for field work. I was also impressed with how well the SSD fit snugly into the drive caddy. Tolerances through the system seem to be engineered very precisely; seams are nice and even, components fit together tightly, and the drive caddy fits into the Samurai with a nice snug click that inspires confidence.

There were some other features about the package that I thought were just plain cool right out of the gate. The battery charger not only has two slots for batteries, but it also charges those two batteries simultaneously, which most dual chargers do not do. Also, Atomos has included four different standards of plug adapters for the charger, so if you’re traveling, you don’t have to worry about powering your Samurai… Just the rest of your gear, which likely did not include this amenity at time of purchase. Yet another nice touch.

I didn’t think I was going to have anything to shoot that first night after getting the Samurai, but as luck would have it, my friend, comedian Jay Whitecotton called, and had something to shoot. We’re working on a documentary together, and it turned out that night was opportune to shoot something. I recorded a single take that was fifty-five minutes long in Apple ProRes422 (HQ). The file size was about 60GB. At the end of the night, the power meter on the Samurai showed that I had used less than 1/4 of one battery. Good power consumption? Check.

The more I use my AJA Ki Pro Mini, the more annoyed I get with it. It doesn’t do anything wrong, per se, or even anything poorly, but its workflow requires a little too much effort for my tastes.

For instance, I really wish it recorded to SSD instead of Compact Flash. I would be happy with one SSD port. But, the thing that really bothers me is how it is so easy to lose recorded clips if you lose power to the unit or if the CF card gets pulled before it has been unmounted. Essentially, the cards mount just like a Mac volume, and if they get yanked without first unmounting them by hitting the SLOT button, then you will assuredly lose at least the last two or three clips that were written to the card. This means that you have to unmount and remount the card after every take if you want to make sure you never lose a file. Too much trouble on a busy set. Plus, someone will inevitably pull power to the unit on occasion, which also really hoses it up.

I think I’m going to order an Atomos Samurai when they start shipping this summer. I glanced at it and talked to the dev team at NAB earlier this year, and the little box shows great promise indeed. I can’t wait to get my hands on one. Has anyone used the Atomos Ninja with an AF100 with good results? How do you handle recording 24p thru the HDMI port? Do you have to do a pulldown in post, and if so, do you see motion jutter? Please let me know, and if you can, send a link to some clips. I wonder if the Ninja would be a good substitute until the Samurai comes out.
